Well Tropjunky, there is nothing ~wrong~ with a normal siphon, it's just a lot more physical work to lug buckets of water around. The python is very convienient and minimizes spills, that makes it easier to do water changes and makes you less likely to procrastinate them. Well, that's what it does for me anyway. I live in an apartment, filling buckets in the tub and then walking them through the house to my tank sucks, and i'm not too strong so i can only carry small buckets, that means many trips back and forth. It does increase your water usage if you use it to drain though, and you'll lose the tankwater down the drain. Occasionally i use a normal siphon to get a bucket of tankwater water to rinse the filter media, and use it to water my houseplants or the ones i keep on the balcony, good gentle fertilizer.
